## New in Current Filing: Failure or perceived failure to meet our ESG goals or expectations set by growing public interest and government regulation of ESG topics could result in reputational harm or adversely affect our business

Costco has set public targets and disclosed intentions for future action regarding sustainability. There are dependencies outside of our control impacting our ability to meet our goals, including but not limited to: economic conditions, ability to access technology at an appropriate cost or scale, the ability to procure sufficient clean energy at competitive market rates to meet future operational and supplier needs, unforeseen operational and implementation challenges, termination or contraction of policies or systems which support our capital investments, and collaboration with third parties. We may not make adequate and timely investments or successfully implement strategies that will effectively achieve our sustainability-related goals, which could lead to reputational harm with members and other stakeholders. 17 17 17 Table of Contents Table of Contents

## New in Current Filing: Risk Management and Global Strategy

We have implemented processes, technologies, and controls to seek to assess, identify, and manage risks associated with cybersecurity threats. Management considers cybersecurity risks within our overall approach to enterprise risk management. We evaluate these risks based on several frameworks, including the National Institute of Standards and Technology (NIST) Cybersecurity Framework (CSF), Center for Internet Security (CIS) 18 Critical Security Controls, and the Payment Card Industry Data Security Standard (PCI DSS). Our governance policies, including our Information Security Policy, outline high-level objectives designed to meet compliance and regulatory requirements. We undertake a bi-annual NIST CSF and CIS 18 Critical Security Controls assessment, conducted by a third-party, to measure our program maturity. We have implemented a variety of technologies, leveraging third-party security providers for some, and engage in multiple activities to seek to identify and mitigate vulnerabilities and risks in systems. These include, among other activities, scanning for common vulnerabilities and exposures, penetration tests on internal and external networks, code scans on applications, allowed application listing, configuration management tools, employee awareness and training, and internal and external audits. We also review, with various frequencies, on a risk-based priority select third parties with whom we do business, in an effort to reduce the likelihood of security incidents or business interruptions. We maintain cybersecurity insurance that would apply to certain losses arising from significant security incidents. We maintain a security operations center, supported by external providers and our employees, which provides threat detection and incident response capabilities. We maintain cyber incident response plans and related playbooks, for execution by our information security team, in coordination with stakeholders (including legal counsel). Significant incidents will be escalated to a Cybersecurity Materiality Committee to assess materiality based on qualitative and quantitative factors. The Committee is composed of a cross-divisional group of executives representing the core business functions of Information Technology and Security, Operations, Administration, Finance and Accounting, and Legal. We conduct periodic tabletop exercises, including at the executive level, to test our response processes and incident management procedures. 18 18 18 Table of Contents Table of Contents Governance Our Board of Directors has delegated certain responsibilities to the Audit Committee of the Board. The Audit Committee reviews and discusses with management the identification and mitigation of cybersecurity risks, including (among other things) the effectiveness of risk-management policies and practices designed to help safeguard our operations, financial systems, and data. Our Vice President of Information Security and Chief Information Security Officer (CISO) presents cybersecurity-related topics, including program maturity progress, regularly to the Audit Committee. The Internal Audit team, in its periodic compliance and risk assessment updates to the Audit Committee, also reports on its reviews of certain of our cybersecurity risk exposures, controls, and management actions. The full Board also receives cybersecurity evaluations from time to time. Our information security organization is led by our CISO, who has over eighteen years of relevant experience, serving in leadership roles across the retail and technology sectors. The CISO is responsible for all aspects of our cybersecurity program, including cybersecurity engineering and architecture, cybersecurity operations, incident response, threat intelligence, identity and access management, cybersecurity risk and compliance, and vulnerability management. Our CISO reports to our Chief Information and Digital Officer (CIDO), who has more than thirty years' experience in which he has led global digital responsibilities, including leading global cyber teams. Our CIDO reports to the Chief Executive Officer.

## New in Current Filing: Risks from Material Cybersecurity Threats

We and our third-party service and merchandise providers have experienced cybersecurity incidents and threats. Based on the information available as of the date of this Form 10-K, we are not aware of any risks from actual cybersecurity incidents that have materially affected us or are reasonably likely to materially affect us, including our business strategy, results of operations, or financial condition. It is possible that there have been intrusions into our systems that have not been identified by our controls and procedures and that might manifest in significant events at a later time. There can be no guarantee that the actions and controls we and our third-party service providers have implemented and are implementing will be sufficient to protect our systems, information or other property. See "Risk Factors" in Item 1A of this Form 10-K for more information on our cybersecurity-related risks. Item 2 - Properties

## No Match in Current: Factors associated with climate change could adversely affect our business.

*This section from the 2023 filing does not have a high-confidence textual match in 2024. It may have been removed, merged, or substantially reworded.*

We use natural gas, diesel fuel, gasoline, and electricity in our distribution and warehouse operations. Government regulations limiting carbon dioxide and other greenhouse gas emissions and other environmental restrictions may increase compliance and merchandise costs, and other regulation affecting energy inputs could materially affect our profitability. As the economy transitions to lower carbon intensity we cannot guarantee that we will make adequate investments or successfully implement strategies that will effectively achieve our climate-related goals, which could lead to negative perceptions among members and other stakeholders and result in reputational harm. Climate change, extreme weather conditions, wildfires, droughts and rising sea levels could affect our ability to procure commodities at costs and in quantities we currently experience. We also sell a substantial amount of gasoline, the demand for which could be impacted by concerns about climate change and increased regulations. More stringent fuel economy standards, changing public policies aimed at increasing the adoption of zero-emission and alternative fuel vehicles and other regulations related to climate change, and evolving consumer preferences will affect our future operations and will adversely impact certain elements of our profitability and require significant capital expenditures. 15 15 15 Table of Contents Table of Contents

## Modified: We may not timely identify or effectively respond to consumer tastes and preferences, which could negatively affect our relationship with our members, the demand for our products and services, and our market share.

**Key changes:**

- Reworded sentence: "Failure to identify timely or effectively respond to changing consumer tastes, preferences and spending patterns including those related to resource efficiency, environmental protection, human rights, and the transition to a low-carbon economy could negatively affect our relationship with our members, the demand for our products and services, and our market share."

**Prior (2023):**

It is difficult to consistently and successfully predict the products and services that our members will desire. Our success depends, in part, on our ability to identify and respond to trends in demographics and consumer preferences. Failure to identify timely or effectively respond to changing consumer tastes, preferences (including those relating to environmental, social and governance practices) and spending patterns could negatively affect our relationship with our members, the demand for our products and services, and our market share. If we are not successful at predicting our sales trends and adjusting our purchases accordingly, we may have excess inventory, which could result in additional markdowns, or we may experience out-of-stock positions and delivery delays, which could result in higher costs, both of which would reduce our operating performance. This could have an adverse effect on net sales, gross margin and operating income.

These include benefits of $54, $94 and $75, related to stock-based compensation.

In 2023 and 2022, the Company had valuation allowances of $422 and $313, primarily related to foreign tax credits that the Company believes will not be realized due to carry forward limitations. The foreign tax credit carry forwards are set to expire beginning in fiscal 2030. The Company generally no longer considers fiscal year earnings of non-U.S. consolidated subsidiaries after 2017 to be indefinitely reinvested (other than China and Taiwan) and has recorded the estimated incremental foreign withholding taxes (net of available foreign tax credits) and state income taxes payable assuming a hypothetical repatriation to the U.S. The Company considers undistributed earnings of certain non-U.S. consolidated subsidiaries, which totaled $3,225, to be indefinitely reinvested and has not provided for withholding or state taxes. A reconciliation of the beginning and ending amount of gross unrecognized tax benefits for 2023 and 2022 is as follows: 20232022Gross unrecognized tax benefit at beginning of year$16 $33 Gross increases - current year tax positions1 1 Gross increases - tax positions in prior years11 12 Gross decreases - tax positions in prior years(11)(12)Gross decreases - settlements -  (12)Lapse of statute of limitations(1)(6)Gross unrecognized tax benefit at end of year$16 $16 54 54 54 Table of Contents Table of Contents The gross unrecognized tax benefit includes tax positions for which the ultimate deductibility is highly certain but there is uncertainty about the timing of such deductibility. At the end of 2023 and 2022, these amounts were immaterial. Because of the impact of deferred tax accounting, other than interest and penalties, the disallowance of these tax positions would not affect the annual effective tax rate but would accelerate the payment of cash to the taxing authority. The total amount of such unrecognized tax benefits that if recognized would favorably affect the effective income tax rate in future periods is $14 and $15 at the end of 2023 and 2022. Accrued interest and penalties related to income tax matters are classified as a component of income tax expense. Accrued interest and penalties recognized during 2023 and 2022, and accrued at the end of each respective period were not material. The Company is currently under audit by several jurisdictions in the United States and abroad. Some audits may conclude in the next 12 months, and the unrecognized tax benefits recorded in relation to the audits may differ from actual settlement amounts. It is not practical to estimate the effect, if any, of any amount of such change during the next 12 months to previously recorded uncertain tax positions in connection with the audits. The Company does not anticipate that there will be a material increase or decrease in the total amount of unrecognized tax benefits in the next 12 months. The Company files income tax returns in the United States, various state and local jurisdictions, in Canada, and in several other foreign jurisdictions. With few exceptions, the Company is no longer subject to U.S. federal, state or local examination for years before fiscal 2018. The Company is currently subject to examination in California for fiscal years 2013 to present. Other Taxes The Company is subject to multiple examinations for value added, sales-based, payroll, product, import or other non-income taxes in various jurisdictions. In certain cases, the Company has received assessments from the authorities. Possible losses or range of possible losses associated with these matters are either immaterial or an estimate of the possible loss or range of loss cannot be made at this time. If certain matters or a group of matters were to be decided adversely to the Company, it could result in a charge that might be material to the results of an individual fiscal quarter or year.

Net cash flows from investing activities also includes purchases and maturities of short-term investments. Capital Expenditures Our primary requirements for capital are acquiring land, buildings, and equipment for new and remodeled warehouses. Capital is also required for information systems, manufacturing and distribution facilities, initial warehouse operations, and working capital. In 2023, we spent $4,323 on capital expenditures, and it is our current intention to spend approximately $4,400 to $4,600 during fiscal 2024. These expenditures are expected to be financed with cash from operations, existing cash and cash equivalents, and short-term investments. We opened 26 new warehouses, including three relocations, in 2023, and plan to open up to 28 additional new warehouses, including one relocation, in 2024. There can be no assurance that current expectations will be realized, and plans are subject to change upon further review of our capital expenditure needs and the economic environment.

Excluding the impact of gasoline price deflation on net sales, gross margin was 10.50%, an increase of two basis points. This two basis point increase was positively impacted by: 18 basis points due to a smaller LIFO charge in 2023 compared to 2022, and seven basis points due to core merchandise categories, predominantly foods and sundries. These were offset by: 16 basis points due to the downsizing and then discontinuation of our charter shipping activities; four basis points due to increased 2% rewards; and three basis points due to warehouse ancillary and other businesses, predominantly e-commerce, partially offset by gasoline and business centers. Changes in foreign currencies relative to the U.S. dollar negatively impacted gross margin by approximately $349, compared to 2022, attributable to our Canadian and Other International Operations. The gross margin in core merchandise categories, when expressed as a percentage of core merchandise sales (rather than total net sales), increased two basis points, driven by foods and sundries and non-foods, partially offset by fresh foods. This measure eliminates the impact of changes in sales penetration and gross margins from our warehouse ancillary and other businesses. Gross margin on a segment basis, when expressed as a percentage of the segment's own sales and excluding the impact of changes in gasoline prices on net sales (segment gross margin percentage), increased in our U.S. segment, due to a smaller LIFO charge and increases in core merchandise categories, primarily foods and sundries, partially offset by the charges related to the discontinuation of our charter shipping activities discussed above and warehouse ancillary and other businesses. Gross margin percentage increased in our Canada segment, attributable to increases in core merchandise categories and warehouse ancillary and other businesses. Our Other International gross margin percentage decreased, largely due to decreases in core merchandise categories, partially offset by warehouse ancillary and other businesses. All segments were negatively impacted by increased 2% rewards.

Excluding the impact of gasoline price deflation on net sales, gross margin percentage was 10.88%, an increase of 31 basis points. This increase was positively impacted by: 19 basis points due to warehouse ancillary and other businesses, primarily e-commerce and gasoline; 16 basis points due to the absence of charges related to the discontinuation of our charter shipping activities that were recorded in the first and third quarters of 2023; and three basis points due to a LIFO benefit. This increase was partially offset by four basis points in our core merchandise categories and three basis points due to increased 2% rewards. The gross margin in core merchandise categories, when expressed as a percentage of core merchandise sales (rather than total net sales), increased 11 basis points. The increase was primarily due to non-foods, partially offset by fresh foods and foods and sundries. This measure eliminates the impact of changes in sales penetration and gross margins from our warehouse ancillary and other businesses. Gross margin on a segment basis, when expressed as a percentage of the segment's own sales and excluding the impact of changes in gasoline prices on net sales (segment gross margin percentage), increased in our U.S. and Canadian segments. Our U.S. segment performed similarly to the consolidated results above. Our Canadian segment gross margin percentage increased, primarily due to increases in core merchandise categories and warehouse ancillary and other businesses, partially offset by increased 2% rewards.

**Prior (2023):**

The 2019 Incentive Plan authorized the issuance of 17,500,000 shares (10,000,000 RSUs) of common stock for future grants, plus the remaining shares that were available for grant and the future forfeited shares from grants under the previous plan, up to a maximum aggregate of 27,800,000 shares (15,885,000 RSUs). The Company issues new shares of common stock upon vesting of RSUs. Shares for vested RSUs are generally delivered to participants annually, net of shares withheld for taxes. Summary of Restricted Stock Unit Activity At the end of 2023, 8,747,000 shares were available to be granted as RSUs, and the following awards were outstanding: •2,869,000 time-based RSUs, which vest upon continued employment or service over specified periods of time; and •176,000 performance-based RSUs, of which 135,000 were granted to executive officers subject to the determination of the attainment of performance targets for 2023. This determination occurred in September 2023, at which time at least 33% of the units vested, as a result of the long service of all executive officers, with the exception of one executive officer who has less than 25 years of service.

The 2019 Incentive Plan authorized the issuance of 17,500,000 shares (10,000,000 RSUs) of common stock for future grants, plus the remaining shares that were available for grant and the future forfeited shares from grants under the previous plan, up to a maximum aggregate of 27,800,000 shares (15,885,000 RSUs). The Company issues new shares of common stock upon vesting of RSUs. Shares for vested RSUs are generally delivered to participants annually, net of shares withheld for taxes. As required by the 2019 Incentive Plan, in conjunction with the 2024 special dividend, the number of shares subject to outstanding RSUs was increased on the dividend record date to preserve their value. They were adjusted by multiplying the number of outstanding shares by a factor of 1.018, representing the ratio of the Nasdaq closing price of $674.62 on December 26, 2023, which was the last trading day immediately prior to the ex-dividend date, to the Nasdaq opening price of $662.70 on the ex-dividend date, December 27, 2023. The outstanding RSUs increased by approximately 52,000. The adjustment did not result in additional stock-based compensation expense, as the fair value of the awards did not change. As further required by the 2019 Incentive Plan, the maximum number of shares issuable under the plan was proportionally adjusted, which resulted in an additional 128,000 RSU shares available to be granted. Summary of Restricted Stock Unit Activity At the end of 2024, 7,278,000 shares were available to be granted as RSUs, and the following awards, adjusted for the effects of the special dividend, were outstanding: •2,677,000 time-based RSUs, which vest upon continued employment or service over specified periods of time; and •122,000 performance-based RSUs, of which 95,000 were granted to executive officers subject to the determination of the attainment of performance targets for 2024, which occurred in September 2024. At that time, depending upon long-service terms, at least 33% of the units vested. The remaining awards vest upon continued employment over specified periods of time.

**Prior (2023):**

Legal Proceedings The Company is involved in many claims, proceedings and litigations arising from its business and property ownership. In accordance with applicable accounting guidance, the Company establishes an accrual for legal proceedings if and when those matters present loss contingencies that are both probable and reasonably estimable. There may be losses in excess of amounts accrued. The Company monitors those matters for developments that would affect the likelihood of a loss (taking into account where applicable indemnification arrangements concerning suppliers and insurers) and the accrued amount, if any, thereof, and adjusts the amount as appropriate. The Company has recorded immaterial accruals with 55 55 55 Table of Contents Table of Contents respect to certain matters described below, in addition to other immaterial accruals for matters not described below. If the loss contingency at issue is not both probable and reasonably estimable, the Company does not establish an accrual, but monitors for developments that make the contingency both probable and reasonably estimable. In each case, there is a reasonable possibility that a loss may be incurred, including a loss in excess of the applicable accrual. For matters where no accrual has been recorded, the possible loss or range of loss (including any loss in excess of the accrual) cannot, in the Company's view, be reasonably estimated because, among other things: the remedies or penalties sought are indeterminate or unspecified; the legal and/or factual theories are not well developed; and/or the matters involve complex or novel legal theories or a large number of parties. The Company is a defendant in an action commenced in July 2013 under the California Labor Code Private Attorneys General Act (PAGA) alleging violation of California Wage Order 7-2001 for failing to provide seating to employees who work at entrance and exit doors in California warehouses. Canela v. Costco Wholesale Corp. (Case No. 2013-1-CV-248813; Santa Clara Superior Court). The complaint sought relief under the California Labor Code, including civil penalties and attorneys' fees. On April 26, 2023, the court entered a final judgment in favor of the Company. The plaintiff appealed the judgment in June 2023. In June 2022, a business center employee raised similar claims, alleging failure to provide seating to employees who work at membership refund desks in California warehouses and business centers. Rodriguez v. Costco Wholesale Corp. (Case No. 22CV012847; Alameda Superior Court). The complaint seeks relief under the California Labor Code, including civil penalties and attorneys' fees. The Company filed an answer denying the material allegations of the complaint. In March 2019, employees filed a class action against the Company alleging claims under California law for failure to pay overtime, to provide meal and rest periods and itemized wage statements, to timely pay wages due to terminating employees, to pay minimum wages, and for unfair business practices. Relief was sought under the California Labor Code, including civil penalties and attorneys' fees. Nevarez v. Costco Wholesale Corp. (Case No. 2:19-cv-03454; C.D. Cal.). The Company filed an answer denying the material allegations of the complaint. In December 2019, the court issued an order denying class certification. In January 2020, the plaintiffs dismissed their Labor Code claims without prejudice, and the court remanded the action to state court. Settlement for an immaterial amount was agreed upon in February 2021. Final court approval of the settlement was granted on May 3, 2022. A proposed intervenor appealed the denial of her motion to intervene, and the appeal was dismissed on February 15, 2023. In May 2019, an employee filed a class action against the Company alleging claims under California law for failure to pay overtime, to provide itemized wage statements, to timely pay wages due to terminating employees, to pay minimum wages, and for unfair business practices. Rough v. Costco Wholesale Corp. (Case No. 2:19-cv-01340; E.D. Cal.). Relief is sought under the California Labor Code, including civil penalties and attorneys' fees. In September 2021, the court granted the Company's motion for partial summary judgment and denied class certification. In August 2019, the plaintiff filed a companion case in state court seeking penalties under PAGA. Rough v. Costco Wholesale Corp. (Case No. FCS053454; Sonoma County Superior Court). Relief is sought under the California Labor Code, including civil penalties and attorneys' fees. The state court action has been stayed pending resolution of the federal action. In September 2023 the parties reached an agreement in principle on a settlement for an immaterial amount. In December 2020, a former employee filed suit against the Company asserting collective and class claims on behalf of non-exempt employees under the Fair Labor Standards Act and New York Labor Law for failure to pay for all hours worked, failure to pay certain non-exempt employees on a weekly basis, and failure to provide proper wage statements and notices. The plaintiff also asserted individual retaliation claims. Cappadora v. Costco Wholesale Corp. (Case No. 1:20-cv-06067; E.D.N.Y.). Based on an agreement in principle concerning settlement of the matter, involving a proposed payment by the Company of an immaterial amount, the federal action has been dismissed.

## Modified: Membership Fees

202320222021Membership fees$4,580$4,224$3,877Membership fees increase8 %9 %9 % 23 23 23 Table of Contents Table of Contents Membership fee revenue increased 8% in 2023, driven by new member sign-ups, upgrades to Executive membership, and the benefit of an additional week. Changes in foreign currencies relative to the U.S. dollar negatively impacted membership fees by $76 compared to 2022. At the end of 2023, our member renewal rates were 92.7% in the U.S. and Canada and 90.4% worldwide. More members auto renewing and higher penetration of Executive members benefit renewal rates. Our renewal rate, which excludes affiliates of Business members, is a trailing calculation that captures renewals during the period seven to eighteen months prior to the reporting date. We account for membership fee revenue on a deferred basis, recognized ratably over the one-year membership period.

202420232022Membership fees$4,828$4,580$4,224Membership fees increase5 %8 %9 % Membership fee revenue increased 5% in 2024, driven by new member sign-ups and upgrades to Executive Membership. These increases were partially offset by one less week of membership fee income in 2024. At the end of 2024, our member renewal rates were 92.9% in the U.S. and Canada and 90.5% worldwide. Renewal rates benefited from higher penetration of Executive members. Our renewal rate, which excludes affiliates of Business members, is a trailing calculation that captures renewals during the period seven to eighteen months prior to the reporting date. Effective September 1, 2024, we increased our membership fees in the U.S. and Canada for Gold Star (individual), Business, and Business affiliates to $65 per year. The Executive membership fee increased from $120 to $130 (membership fee of $65, plus Executive upgrade of $65), and the maximum annual 2% reward associated with the Executive Membership increased from $1,000 to $1,250. We account for membership fee revenue on a deferred basis, recognized ratably over one year. We expect these fee changes to increase revenues approximately $370 over the next two years, $190 of which will benefit fiscal 2025, primarily in the latter half of the year.

## Modified: Changes in or failure to comply with environmental, social, or governance (ESG) regulations could adversely impact our business, financial condition and results of operations.

**Key changes:**

- Reworded sentence: "We are subject to a wide and increasingly broad array of laws and regulations globally relating to ESG matters, including disclosure and compliance requirements."
- Added sentence: "Natural gas, diesel fuel, gasoline, and electricity are used in our operations, distribution channels, and value chain."
- Added sentence: "Government regulations limiting carbon dioxide and other greenhouse gas emissions and other environmental restrictions may increase compliance, operations, and merchandise costs, and other regulations affecting energy inputs could materially affect our profitability."
- Added sentence: "More stringent fuel economy standards, changing public policies aimed at increasing the adoption of zero-emission and alternative fuel vehicles, and other regulations related to climate change may affect our future operations, adversely impact certain elements of our profitability, and require significant capital expenditures."

**Prior (2023):**

We are subject to a wide and increasingly broad array of federal, state, regional, local and international laws and regulations relating to the use, storage, discharge and disposal of hazardous materials, hazardous and non-hazardous wastes and other environmental matters. Failure to comply with these laws could result in harm to our members, employees or others, significant costs to satisfy environmental compliance, remediation or compensatory requirements, or the imposition of severe penalties or restrictions on operations by governmental agencies or courts that could adversely affect our business, financial condition and results of operations. Operations at our facilities require the treatment and disposal of wastewater, stormwater and agricultural and food processing wastes, the use and maintenance of refrigeration systems, including ammonia-based chillers, noise, odor and dust management, the operation of mechanized processing equipment, and other operations that potentially could affect the environment and public health and safety. Failure to comply with current and future environmental, health and safety standards could result in the imposition of fines and penalties, illness or injury of our employees, and claims or lawsuits related to such illnesses or injuries, and temporary closures or limits on the operations of facilities.

**Current (2024):**

We are subject to a wide and increasingly broad array of laws and regulations globally relating to ESG matters, including disclosure and compliance requirements. These laws and regulations, along with expanding voluntary reporting, are expanding the scope and complexity of matters that we are required to regulate, assess, and disclose and potentially limit our sourcing flexibility. Failure to comply with these laws could result in harm to our members, employees, workers in the value chain or others, significant costs to satisfy environmental compliance, remediation or compensatory requirements, or the imposition of severe penalties or restrictions on operations by governmental agencies or courts that could adversely affect our business, financial condition and results of operations.
